Phone app is utter *******

for months i been getting marketing BS texts from standard bank, about how great their new phone app is, but i Spent an hour on the phone with paul from Vaf today because it sux,story is on 26 January -15 i made a payment to VAF using the wonderful phone app that they think they have, then last few days i start getting texts of how my vaf account is behind? they haven't received the last 2 payments?,Er what? the phone app has VAf listed as a beneficiary? i gave them a reference number that was paid,but that's NO GOOD, Now i have to take time off work go into a branch, pay money out of my account to print a proper headed statement , spend my money to fax it to VAF, all to prove that i used SB phone app to pay SB VAF? anyone here think thats right?, because their phone app just lists the reference number i cant print it or get more details, or forward it, All for my safety security and protection? these guys are victims of their own marketing,
